DENVER - Police are searching for the two suspects who fired shots during the 4/20 pot rally in Denver's Civic Center Park on Saturday, injuring three people and causing thousands of festival-goers enjoying the jovial atmosphere to flee in panic.

A man and woman, between 20 and 30 years old, were shot in the leg, Denver police tweeted. Their injuries were considered non life-threatening.

A third victim, a juvenile, was grazed by a bullet and walked into a nearby hospital, police tweeted.

A dog, belonging to one of the victims, also appeared to have been grazed or shot and was seen limping from the scene. Several other people suffered some minor injuries from running or being trampled, according to witnesses who talked to 7NEWS.

Police asked those attending the rally for possible photo or video of the shootings, and had no immediate motive for the shooting. [via Denver TV station]

If for no other reason, people are going to track these shooters down for wounding the dog.
